The 31-year-old, who has scored 26 times in 33 internationals, is looking to sharpen up his game ahead of this summer's World Cup in Russia.

"It was agreed with Manchester United for Mohammed Al-Sahlawi to join for a training programme for three weeks, may God benefit him," Turki Al-Sheikh, chairman of the General Sports Authority (GSA) of Saudi Arabia, wrote on Twitter.

Al-Sahlawi is to spend three weeks training with Manchester United

The arrangement is part of a commercial agreement with the Old Trafford club and sporting authorities in Saudi Arabia, where Al-Sahlawi plays for Al-Nassr.

In October, United signed a memorandum of understanding with GSA which will see the club help develop the Saudi football industry, as part of its 2030 Vision - the plan to diversify the Saudi economy and to develop its public sectors announced in 2016 by Crown Prince Mohammad bin Salman.

Saudi Arabia were drawn in Group A for this summer's tournament alongside hosts Russia, Egypt and Uruguay.
